CAR-ROOF.

Application filed November 24, 1913.

To all whom it may concern:

Be it known that I, RICHARD IVEBB BUR- NETT, a citizen of the UnitedStates of America, residing at Montreal, in the Province of Quebec andDominion of Canada, have invented certain new and useful Improvements inCar-Roofs, of which the following is a specification, reference beinghad therein to the accompanying drawings.

The invention relates to car roofs of that type in which the loadsustaining roofing plates are arranged beneath the hollow carlines, andare supported and weather proofed by means located within said carlines.It is the particular object of the pres ent invention to facilitate theconstruction, assembly and repair of the roof by an improvedconstruction of supporting means for the roofing plates, said meanspermitting of quickly attaching and detaching said plates, and alsoproviding increased flexibility inthe roof structure.

In the drawings:

Figure 1 is a longitudinal section through a portion of the roof showingone of the carlines and the engagement of the roofing plates therewith;

Fig. 2 is a bottom plan view of a portion of the carline showing thesupporting means for the roofing plates; and

Fig. 3 is a perspective View of the hanger support detached from thecarline.

A is a hollow carline which, as shown and preferably constructed, is ofan inverted U- shaped cross section having laterally-extending bottomflanges B. C are roofing plates formed of relatively heavy gage metaland arranged in a plane beneath the flanges B. The edges of these platesare provided with upturned flanges C, which extend within the hollowcarline, and the upper ends of said flanges are provided withreturn-bends D which lie adjacent to each other. The sheets aresupported by saddles E arranged beneath the returnbends D, said saddlesin turn being supported by hanger bolts F supported by bearings at ahigher point than the hollow carlines.

To facilitate the assembly of the parts and also repair when necessary,it is desirable to detachably engage the hanger F with its supportingbearing. It is also desirable to avoid the perforation of the carline,as th1s in a measure destroys its weather-proofing character. I havetherefore devised a conjacent to the sides of said carline.

flanged portions are then attached to the car- Specification of IlettersPatent. Patented Aug, 21 1917.

struction of hanger support which is secured within the hollow carlinewithout any perforation of the latter, and which is so formed as topermit of engaging and disengaging the hanger. Specifically, the hangersupport' G is preferably formed of a metallic strap having the webportion G extending across the space within the hollow carline andflanged portions G which lie ad- These line, preferably by spot welding,which secures the same without puncturing the car line walls. The webportion G is formed with a slot H therein, which extends to one edge andforms .an entrance orifice for engaging the hanger bolt F. The shank ofthis bolt loosely fits within the slot, while the head portion F restsupon the web G. The saddle D is secured to the hanger bolt, preferablyby providing a slot I in the latter, through which a key J may be drivento extend longitudinally of the carline.

With the construction as described, in assembling the roof, the hangerbolts F are first engaged with the supporting seats G by inserting themin the slots H. The plates C may then be engaged with the hangers byregistering the apertures in the return bent flanges D with the lowerends of the shanks and then pressing the plates upward. The saddles arethen sleeved upon the hangers and are secured by the keys J, which aredriven in the slots I. 1

WVhen the roof is in service a limited freedom of movement of the platesC is permitted by the hangers which are free to adjust themselveslongitudinally of the slots H to compensate for weaving stresses in thecar frame.

What I claim as my invention is:

1. In a car roof, the combination with a hollow carline of loadsustaining roofing sheets having a limited freedom of movement andprovided with portions extending upward into said hollow carline, ahanger for supporting said sheets engaging said upwardly extendingportions, and a seat for said hanger comprising a strap extending acrossbetween the side walls of the 'carline and secured thereto, said strapbeing pro-.

vided with an entrance slot for the hanger. I

2. In a car roof, the combination with hollow carlines, of loadsustaining roofing sheets having a limited freedom of movement andprovided with portions extending upward in said carlines, a saddle onwhich said upwardly extending portions are supported, a headed hangerfor said saddle, and a seat for said hanger bolt comprising a strapextending across between the side walls and secured thereto, said straphaving an open-ended slot extending centrally thereof and longitudinallyof the carline forming a seat for adjustably engaging the hanger head.

3. In a car roof, the combination with a hollow carline, of loadsustaining roofing sheets having a limited freedom of. movement andprovided with portions extending upward in said carline, a saddle forsupporting said upwardly-extending portions, a

headed hanger bolt engaging said saddle, and a seat for said hangerbolt, comprising a U-shaped strap extending across the holloW carline,the sides of said strap being spot Welded to said carline and the webportion of said strap being provided with an open-ended slot extendingcentrally thereof and longitudinally of the carline, and forming a seatfor adjustably engaging the hanger head.

In testimony whereof I allix my signature in presence of two witnesses.
